You might be missing a number on the code.
Lots of codes start with 121...
Maybe your code is a 121x?

That's the code INPA gave me.

It translates to “height adaptation error”
I’ve not heard of it.
Wish I could help....

Yes, that is correct. I'm sure it has to do with air density more than anything which may point to the MAF. I am under the impression a bad MAF would throw different codes and have poor off-idle performance as well.
